The official Transformers 4 revealed keep coming as Michael Bay has announced that the Pagani Huayra will feature in the fourth live-action Transformers movie.

"Considered a masterpiece of design and engineering, this fierce, 2013 blood red Pagani Huayra, is named after an ancient Andean God of Wind. High resolution photo: http://bayhem.com/15BERvQ" posts Michael on his website.

A pair of photos posted on Instagram by Nicole_4_Eva from the Lockhart, Texas set of Transformers 4 have revealed that actor Titus Welliver is on set with Jack Reynor and Mark Wahlberg.  There had been no previous reports of Mr Welliver being tied to Transformers 4, so his actual role on the movie is very much unknown.

Michael Bay has posted a new image to his Flickr account of the Chevrolet Sonic RS with the caption "The Ultimate Sonic RS, just pure fun.". This is agood sign that the vehicle will feature within Transformers 4 in one form (as a Transformer or being the vehicle of a human) or another.  You can view the image below.

Instagram has once again played host to more on-set image from Transformers 4 .  Thisi time showing the orignial Optimus Prime and Bumblebee vehicles.

Does this mean the two will appear in flashbacks, or will they start the movie in their old forms and then Transscan into the new forms?

Originally denied by Nelson, he later all but confirmed that Mega Fox will be returning in Transformers 4

Megan Fox is currently filming Michael Bay's Teenage Mutant Ninja Turtles in which she will play April O'Neil.

Michael Bay has revealed another vehicle which will be used for Transformers 4 as the 2013 Lamborghini Aventador LP 700-4 Coupe.  Mr Bay made the announcement on his website today with the text "Unveiling yet another surprise . . . the extraordinary and exhilarating 2013 Lamborghini Aventador LP 700-4 Coupe. High resolution photo: http://bayhem.com/16OKk8T"

Could this be a new Sideswipe or could it be a Decepticon, Lockdown perhaps? Time will reveal all.

Update

Michael Bay has also posted a new groupshot of the Autobots over on his Flickr account on the 1st June which is missing both the Lamborghini and what appeared to be Ratchet who is yet to be officially announced and was spotted at the back of the original groupshot image by HotshotsWorldWide

Last night Michael Bay confirmed that the military truck which was revealed as an Autobot in recent on-set images will indeed be called Hound.  The bio on Mr Bays's website read as "The always rugged and reliable Hound, one of the Family of Medium Tactical Vehicles from Oshkosh Defense. High resolution".  We'd expect Hasbro to release a "Roadbuster" style recolour either as Roadbuster or as "Roadbuster Bulkhead" when a toy is eventually released.

In releated news, Fox Detroit have posted a video, which can be viewed below, regarding the recent Transformers 4 casting call which took place in Michigan. The report states that Michael Bay will be stepping up his filming within the area including using the location to shoot parts of the story which will be set within Hong Kong.

Joblo.com, the website that previously reported rumors regarding the identities of several new characters to be included in Transformers 4, is now claiming to know the names of the two Auotbot vehicles that were revealed yesterday. According to their source the Bugatti Grand Sport Vitesse is Drift, and the 2014 Concept C7 Corvette Stingray is Slingshot.

Drift may well be the rumoured  "Samurai  looking to regain his honor by joining the Autobots" character, which would kind of tie in to the IDW Character of the same name. 

Nelson, admin of Shoot for the Edit, has pointed out that production names do not always end up being final names .. though it's probably unlikey they would change 

Yahoo! was broke the new of two new cars which will be used in Transformers 4. The vehicles were photographed on the border of Arizona and Utah were the 2013 Bugatti Veyron Grand Sport Vitesse, a $2.5 million dollar car, as well as a 2014 C7 Corvette Stingray concept.  It has been confirmed that these cars are indeed Autobots with Bay's official website though their names have not been given at this time.

Hollywood reporter has announced that actor T.J. Miller has signed onto Transformers 4 to play the best friend of Mark Wahlberg's character's.  T.J's character will be a mechanic.

Finally a photo was posted on Instagram which has shown a new truck mode for Optimus Prime. Michael Bay posted that the truck is "completely upgraded, custom-built Optimus Prime from Western Star (a subsidiary of Daimler Trucks North America)."

Joblo have posted an article from a "source" claiming to confirm who some of the Transformers will be appearing in the latest live action movie.  This should very much be taken with a pinch of salt as the script it's supposedly from could easily be a fan produced piece of fiction.  For those not wanting to be spoilt, look away now.

From Joblo:

That's right, folks, our source has confirmed that TRANSFORMERS 4 will feature none other than the famed Dinobots, including fan favorite Grimlock. No word on whether he'll retain his neanderthal voice, but one can only hope he does as that's a true staple of the character. One of the villains of the film will be a character named Lockdown, who has a ship full of decommissioned Transformers, including the dinobots, which are somehow brought back to life by a captured Optimus Prime. Prime is joined by returning autobot Bumblebee and at one point both characters (and potentially others) will "ride" the Dinobots into battle in Hong Kong (which fits well within the announcement that the film would film partially in China), with Prime on Grimlock and Bumblebee on a Pterandon, presumably Swoop.

Additionally, the autobot Hound will make his debut, as well as a former "Samurai" Decepticon that wants to regain his honor and become an Autobot (UPDATE: Source confirms this is Drift). And what about Megatron, who is presumed dead after the last film? Well, fans of TRANSFORMERS: THE MOVIE will be happy to know that not only will the dinobots be making their debut, but also Galvatron, who is basically Megatron "reborn" (and originally voiced by the first Spock, Leonard Nimoy).

So those characters who are listed are:

1. Optimus Prime
2. Grimlock
3. Swoop (assumed)
4. Lockdown
5. Bumblebee
6. Hound
7. Drift
8. Galvatron

Deadline reports that actor Kelsey Grammer has signed on to be the main human villain in Transformers 4.

"Kelsey Grammer is embracing his inner bad guy. After his Golden Globe turn as the ruthless politician in Boss, Grammer has just landed the key villain role in Michael Bay‘s next Transformers film, which stars Mark Wahlberg and Stanley Tucci. I’m told that Grammer will play Harold Attinger, a counter intelligence guy."

The news has split fans with some deciding to docus focus on the term key villain suggest that it means even less screen-time for giant robots, where as in truth nothing it is known about the storyline to justify these fears.
